Engineering the optical properties of nickel sulphide thin films by zinc integration for photovoltaic applications.

Thin films of binary nickel sulphide (NiS) and zinc-doped ternary nickel sulphides (NiZnS, where = 0-1) were effectively produced by the chemical bath deposition method, and their potential use in photovoltaics were investigated. Dopant inclusion did not change the crystal structure of NiS, according to the structural analysis of the synthesized samples. They are appropriate for solar cell applications since the morphological study verified the crack-free deposition.
